DETAILED DESCRIPTION

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-Figure 5The present embodiment provides a cooling device suitable for heat treatment, including a cooling tank 1 with quenching oil inside, a limiting component 2 and a water supply component. The cooling tank 1 is provided with a cooling groove and a drain hole, the cooling groove is arranged around the side wall of the cooling tank 1, the water supply component is connected with the cooling groove through a water pipe, and the water supply component continuously provides cooling water into the cooling groove; the limiting component 2 includes a baffle plate 201, a limiting unit and a limiting block 202, the drain hole is arranged beside the connection between the water pipe and the cooling tank 1, the baffle plate 201 is sealed and arranged in the cooling groove, and the baffle plate 201 is located between the drain hole and the connection between the water pipe and the cooling tank 1; the cooling tank 1 is also provided with a moving groove, the two ends of the moving groove are respectively connected with the interior of the cooling tank 1 and the cooling groove, and the limiting unit is arranged In the movable groove, one end of the limiting unit can be telescopically arranged inside the cooling tank 1, and the other end thereof is connected to the limiting block 202. The limiting block 202 can be slidably arranged at the connection between the cooling tank and the water pipe, and the limiting block 202 can lock or release the sealing relationship between it and the connection between the cooling tank and the water pipe; by providing a water supply component, the function of the water supply component is to transport cooling water into the cooling tank, and the heat of the quenching oil in the cooling tank 1 is transferred to the cooling water, so as to reduce the temperature of the quenching oil; and when the cooling water circles around the setting direction of the cooling tank, it will be discharged from the cooling tank 1 through the discharge hole; in addition, a limiting component 2 is also provided, and the limiting component 2 includes the limiting block 202, and the function of the limiting block 202 is to lock or release it and The sealing relationship between the connection between the cooling trough and the water pipe; specifically, when the workpiece is placed in the cooling tank 1 for cooling treatment, a large amount of oil fume exhaust gas will be generated, and the temperature of the quenching oil will also increase, thereby increasing the force of the quenching oil on the limiting unit, driving the limiting unit to move, and then the limiting unit drives the limiting block 202 connected thereto to move, so that the limiting block 202 releases the sealing relationship between the connection between the cooling trough and the water pipe, and the water supply component can smoothly transport cooling water into the cooling trough; after the temperature of the quenching oil drops, the oil fume exhaust gas will also dissolve in the quenching oil due to the drop in the temperature of the quenching oil, which not only causes the air pressure in the cooling tank 1 to decrease, but also reduces its effect on the limiting unit due to the decrease in the temperature of the quenching oil. The limiting unit is reset by the action of force, and the limiting block 202 connected thereto will re-lock the sealing relationship between the connection between the limiting block 202 and the cooling trough and the water pipe. The water supply component cannot continue to transport cooling water into the cooling trough, which solves the problem that the existing cooling devices for heat treatment place the heat-treated workpiece in the quenching oil for cooling. In order to avoid the problem that the temperature of the quenching oil is too high and the cooling effect of the quenching oil on the heat-treated workpiece is reduced, the inner wall of the cooling device is filled with cooling water in advance; during the cooling process, the heat of the quenching oil is transferred to the cooling water to achieve the cooling of the quenching oil; but this cooling method requires replacing the cooling water on the inner wall of the cooling device after the cooling process is completed, which makes the cooling process more complicated and reduces the quenching efficiency.

[0022] Specifically, in order to improve the cooling effect of cooling water on quenching oil, the cooling tank 1 of this scheme is provided with a plurality of cooling grooves and a plurality of movable grooves, and the limiting components 2 are provided with a plurality of groups. The plurality of cooling grooves are arranged at equal intervals along the vertical height direction of the cooling tank 1, and the plurality of movable grooves and the plurality of cooling grooves are matched one-to-one. Any movable groove is interconnected with the corresponding cooling groove, and the plurality of movable grooves are not interconnected; the plurality of limiting components 2 are matched one-to-one with the plurality of movable grooves, and any limiting component 2 can be slidably arranged in the corresponding movable groove; by providing cooling grooves in the side walls of the cooling tank 1 at different heights, the coolant at each height can cool the quenching oil in the cooling tank 1, thereby improving the cooling speed and cooling efficiency of the quenching oil by the cooling water.

[0023] Specifically, the limiting unit of the present scheme includes a limiting rod 203, a driving block 204 and a limiting spring 205. The limiting rod 203 is slidably arranged in the movable groove. The two ends of the limiting rod 203 are respectively connected to the driving block 204 and the limiting block 202.

[0024] In order to ensure that the workpiece at high temperature can be safely placed in the cooling tank 1, the present scheme is also provided with a lifting assembly 3, the lifting assembly 3 includes a rotating motor 301, a rotating rod 302 and a plurality of steel ropes 303, the rotating motor 301 is arranged at the top of one end of the cooling tank 1, the rotating rod 302 is arranged horizontally, and the rotating rod 302 is coaxially connected to the output end of the rotating motor 301; a plurality of steel ropes 303 are arranged on the rotating rod 302 along the axial direction of the rotating rod 302, one end of the steel rope 303 is wound around the rotating rod 302, and the other end thereof can lock or release the connection relationship with the workpiece to be cooled; by providing the lifting assembly 3, the lifting assembly 3 controls the height of the workpiece to be raised or lowered by the rotation of the rotating motor 301, and this step replaces the manual placement of the workpiece in the cooling tank, thereby improving the safety of the workpiece placed in the cooling tank.

[0025] According to the above embodiments, when the cooling tank 1 is cooling the workpiece, the interior of the cooling tank 1 needs to be in a sealed state, and the lifting component 3 needs to transport the workpiece outside the cooling tank 1 to the interior of the cooling tank 1. In order to solve this problem, the cooling tank 1 includes a cooling shell 101 with quenching oil inside and a cooling cover 102. The cooling cover 102 can be slidably arranged on the top of the cooling shell 101, and the cooling cover 102 can lock or release its sealing cooperation relationship with the cooling shell 101; when the workpiece is not cooling, the cooling cover 102 releases its sealing cooperation relationship with the cooling shell 101 by sliding, so that the lifting component 3 can smoothly transport the workpiece to the interior of the cooling shell 101; after the workpiece is inside the cooling shell 101, the cooling cover 102 re-locks its sealing cooperation relationship with the cooling shell 101 by sliding, so that when the cooling tank 1 is cooling the workpiece, the interior of the cooling tank 1 is in a sealed state.

[0026] Specifically, due to the presence of the steel rope 303, when the cooling cover 102 slides toward the cooling shell 101, the cooling cover 102 and the steel rope 303 are abutted against each other, thereby causing a gap between the cooling cover 102 and the cooling shell 101. Based on this, in order to solve this problem and further improve the sealing effect between the cooling cover 102 and the cooling shell 101; the cooling cover 102 of the present scheme is provided with a plurality of sealing grooves, and the plurality of sealing grooves and the plurality of steel ropes 303 are matched one-to-one, and the axial direction of the sealing groove is the same as the axial direction of the cooling cover 102, and the central axis of any sealing groove and the central axis of the corresponding steel rope 303 are in the same vertical plane; it also includes a plurality of sealing components 4, and the plurality of sealing components 4 are matched one-to-one with the plurality of sealing grooves, and any sealing component 4 is arranged at the corresponding sealing Groove; a mating groove is provided on the side wall of the sealing groove; the sealing assembly 4 includes a sealing plate 401 and a sealing spring 402, the sealing plate 401 can be slidably sealed in the corresponding mating groove, the sealing spring 402 is provided in the mating groove, the two ends of the sealing spring 402 are respectively connected to the sealing plate 401 and the cooling cover 102, and the sealing plate 401 can lock or release its sealing mating relationship with the corresponding sealing groove; in addition, it is also worth mentioning that a sealing groove hole is provided on the end of the sealing plate 401 close to the corresponding steel rope 303 of the present scheme, and the sealing groove hole can lock or release its sealing mating relationship with the steel rope 303; by providing the sealing groove hole, when the sealing plate 401 is sealed in cooperation with the sealing groove, the sealing groove hole and the steel rope 303 cooperate with each other, so that the cooling cover 102 and the steel rope 303 form a sealing mating relationship together.

[0027] In addition, it should be noted that the position of the steel rope 303 of the present embodiment is fixed, and since the cooling cover 102 is a slidable structure, the position of the sealing slot hole set on the cooling cover 102 is movable. In order to ensure that the sealing slot hole and the steel rope 303 are sealed and matched with each other, the end face of the cooling cover 102 and the end face of the cooling shell 101 are arranged to fit each other, the sealing component 4 of the present embodiment also includes a telescopic block 403, a telescopic spring 404 and a hinge rod 405. A plurality of telescopic slot holes are provided at one end of the cooling cover 102 that fits with the cooling shell 101. The plurality of telescopic slot holes are matched with a plurality of sealing components 4 in a one-to-one manner. Any telescopic block 403 can be telescopically arranged in the corresponding telescopic slot hole; the telescopic spring 404 is arranged in the telescopic slot hole, and the two ends of the telescopic spring 404 are respectively connected to the telescopic block 403 and the cooling cover 102; the telescopic slot hole and the matching slot are communicated with each other, and the hinge rod 405 is arranged at the connection between the telescopic slot hole and the matching slot. The two ends of 05 are respectively hinged to the telescopic block 403 and the sealing plate 401; the telescopic block 403 can lock or release its contraction in the corresponding telescopic slot; by providing the telescopic block 403, as the cooling cover 102 moves toward the direction close to the cooling shell 101, the telescopic block 403 is firstly arranged in contact with the end surface of the cooling shell 101, thereby forcing the telescopic block 403 to contract in the direction of the cooling cover 102, and due to the movement of the telescopic block 403, the hinge rod 405 hinged to the telescopic block 403 is rotated, and the hinge rod 405 drives the sealing plate 401 hinged thereto to move in the direction of extending out of the matching slot; until the telescopic block 403 is completely contracted into the telescopic slot, the hinge rod 405 is transformed from the original inclined state into a relationship in which its two ends are respectively perpendicular to the telescopic block 403 and the sealing plate 401, and at the same time, the sealing plate 401 hinged to the hinge rod 405 forms a sealing cooperation relationship with the sealing slot.

[0029] In addition, since a large amount of oil fume exhaust gas is generated when the workpiece is cooled, the pressure in the cooling tank 1 increases. In order to ensure that the oil fume exhaust gas in the cooling tank 1 cannot overflow from the joint between the steel rope 303 and the flexible block 501 during the period when the internal pressure of the cooling tank 1 increases, the locking unit of this scheme also includes a locking block 502, a locking spring 503, a pushing spring 504, a pushing block 505 and hydraulic oil 506. The cooling cover 102 is provided with a locking slot, and the two ends of the locking slot are respectively connected to the sealing slot and the interior of the cooling shell 101. The locking block 502 is slidably sealed at one end of the locking slot close to the interior of the cooling shell 101, and the pushing block 505 is slidably sealed at one end of the locking slot close to the sealing slot. The locking slot, the locking block 502 and the pushing block 505 together form a hydraulic space. Hydraulic oil 506 is filled in the hydraulic space, and the locking spring 503 and the pushing spring 504 are both arranged in the locking slot, and the two ends of the locking spring 503 are respectively connected to the locking block 502 and the cooling cover 102; the two ends of the pushing spring 504 are respectively connected to the pushing block 505 and the cooling cover 102; by providing the locking block 502, the pushing block 505 and the hydraulic oil 506, when the air pressure inside the cooling tank 1 increases, the locking block 502 will be pushed back into the locking slot, and then the pushing block 505 will be driven to move in the direction of the sealing slot, and since the pushing block 505 is connected to the flexible block 501, the contact force between the flexible block 501 and the steel rope 303 is increased, ensuring that the oil fume exhaust gas in the cooling tank 1 cannot overflow from the contact between the steel rope 303 and the flexible block 501 during the period when the internal pressure of the cooling tank 1 increases.
